Many of the technologies we use every day consume a lot more resources and power than they need to, and using and manufacturing them can create a mess. Here are a few of the ways that technology can harm the environment:
Pollution - Air, water, heat and noise pollution can all be caused by producing and using technology
Consuming resources - Non-renewable resources, including precious metals like gold, are used to make technology. Many others, such as coal, are consumed to generate the electricity to use technology. Even some renewable resources, like trees and water, are becoming contaminated or are used up faster than they can renew themselves because of technology.
Waste - Manufacturing technology creates large amounts of waste, and used computers and electronics get thrown out when they break or become outdated. Called "technotrash," these electronics contain all sorts of hazardous materials that are very unsafe for the environment. They need to be disposed of using special methods.
Disrupting ecology - Clearing land where animals used to live to build factories and allowing pollution to contaminate the food chain can greatly affect the environment's natural cycles.
Health hazards - Using toxic materials that can harm our health can cause cancer, and technology addiction can lead to other health problems like obesity and carpal tunnel syndrome.
You can encourage manufacturers by choosing to buy more energy-efficient and less hazardous electronics and by supporting companies that make protecting the environment a priority. You can also do your own part to reduce environmental impact by not being wasteful and disposing of your electronics safely and properly.
xavier5386 on 18 Feb 13This article is basically about physcist developing a system in witch they use the suns energy to destroy or redirect asteroids from space. The earth at this period of time can easily be destroyed but a random asteroid from outer space. Asteroids are roughly the size of five football flieds long. The earth has recently dodged two asteroid threats on its own but may not be so lucky in the future. This is why Physicists Philip Lubin of University of California, Santa Barbara and Gary Hughes of California Polytechnic State University, San Luis Obispo started working on the DE-STAR proposal a year ago. Directed Energy Solar Targeting of Asteroids, an exploRation (DE-STAR). This system will use the suns solar energy to power a laser beam that can be used to shoot to destroy or redirect future asteroids that have been predicted to come and are a threat to human survival. For example asteroid 2012 DA14-a medium sized, 150 ft (50 m) rock weighing 143,000 tons-was closing in on us. They knew that it would miss us too, by 17,200 miles (27,700 km
